Homoioptoton

Homoioptoton (ho-mee-op-to’-ton): The repetition of similar case endings in adjacent words or in words in parallel position.

Note: Since this figure only works with inflected languages, it has often been conflated with homoioteleuton and (at least in English) has sometimes become equivalent to simple rhyme: “To no avail, I ate a snail.”

I have often thought that ‘something’ is like the stuff stuffed in sausages by somebody some place, where vagueness might fill an empty thing that does not sting, that has no weight, that could be a sort of freight shipped on a shadow cast on moving liquid with an underneath beneath it.
